Ptc Resettable Fuses Procurement Notes

Verify component authenticity through authorized distributors to ensure compliance with RoHS standards. Confirm that the specific suffix matches project requirements, as packaging variations may exist. Cross-reference datasheet electrical characteristics against design constraints before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when circuit design demands a resettable protection mechanism with a 60 VDC limit. Ensure the operating current remains below the 500 mA holding threshold while accounting for ambient temperature derating curves. Validate that the 1 A trip current aligns with the protected load's surge capabilities.

Ptc Resettable Fuses Part Context

This part belongs to the YAGEO SMD2920 series of resettable fuses. The series offers various current ratings within the same 2920 case size, allowing designers to standardize footprints across different product lines while adjusting protection thresholds based on specific application current requirements.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other manufacturers' PPTC devices in the 2920 package with equivalent 60V and 500mA specifications. Verify that alternative parts match the 1A trip current and 4-second response time to maintain system safety integrity.
